OPERATION
Once the piping connections are made and checked you
can run the pumps.
Piggyback Switch Operation – Plug the piggyback switch
into a dedicated grounded outlet and then plug the pump
into the switch. Test the pump by filling the wetwell until
the pump goes On. If the pumps run but fail to pump,
they are probably air locked, drill the relief holes per the
instructions in the Piping Section.
Check the operating range to insure a minimum one min-
ute run time and that the pump goes Off in the correct
position. Note: Small package systems will normally have
a fast ON-OFF cycle.
Control Panel Operation – Fill the wetwell with clear
water.
Use the pump H-O-A (Hand-Off-Automatic) switches
in Hand to test the pumps. If they operate well in Hand
proceed to test Automatic operation. If the pumps run
but fail to pump, they are probably air locked, drill the
relief holes per the instructions in the Piping Section.
Place Control Panel switch(es) in Automatic position and
thoroughly test the operation of the ON, OFF, and Alarm
floats by filling the wetwell with clear water. Important:
Failure to provide a Neutral from the power supply to
a 1Ø, 230 volt Control Panel will not allow the panel
control circuit to operate. The Neutral is necessary to
complete the 115 volt control circuit.
Check voltage and amperage and record the data on the
front of this manual for future reference. Compare the
amperage readings to the pump nameplate maximum
amperage. If higher than nameplate amperage investigate
cause. Operating the pump off the curve, i.e. with too
little head or with high or low voltage will increase am-
perage. The motor will operate properly with voltage not
more than 10% above or below pump nameplate ratings.
Performance within this range will not necessarily be the
same as the published performance at the exact rated
nameplate frequency and voltage. Correct the problem
before proceeding.
Reset the Alarm circuit, place pump switch(es) in the
Automatic position and Control Switch in ON position.
The system is now ready for automatic operation.
Explain the operation of the pumps, controls and alarms
to the end user. Leave the paperwork with the owner or
at the control panel if in a dry, secure location.
The power to the outlet should be Off at this point. The
dedicated outlet should supply power only to the pump.
Our sump pumps have either a single power cord for
pumps with built-in switches or two power cords for
pumps with piggyback switches:
Built-In/Single Cord - plug the single power cord into
a dedicated power outlet.
Piggyback/Two Power Cords - insert the piggyback
switch male plug into a dedicated power outlet. You
then plug the standard male pump plug into the back,
female side, of the piggyback switch plug.
Fasten the power cords to the discharge pipes using tie
wraps or electrical tape. Coil and store any excess power
cord outside the sump.
INSTALLATION
STANDARD PUMP INSTALLATION
Connect the pump(s) to the guide rail pump adapters
or to the discharge piping. Guide rail bases should be
anchored to the wetwell floor.
Complete all wiring per the control panel wiring dia-
grams and NEC, Canadian, state, provincial and/or local
codes.
DO NOT PLACE HANDS IN PUMP
SUCTION WHILE CHECKING
MOTOR ROTATION. TO DO SO
WILL CAUSE SEVERE PERSONAL
INJURY.
Lower the pump(s) into the wetwell.
Check to insure that the floats will
operate freely and will not contact the
piping.
PRE-PACKAGED SYSTEM INSTALLATION
Connect the piping per local codes and the drawings in
Typical Drawings Section.
Sink Drain Systems – Inspect unit for damage. Return
damaged units to the distributor. Install on solid, level
ground. Hand tighten the piping into the Inlet. Con-
nect the Discharge to the main drain line. The discharge
should contain a union and a check valve. See Typical
Installation Drawing 2.
Packaged Sewage Systems – Inspect unit for damage.
Return damaged units to the distributor. Install on solid,
level ground. Remove all tape from discharge pipe, vent
hole, float switch and inlet. Check to insure that the float
swings freely and is attached to the pump. Install the
grommet in the inlet hole and lubricate it before install-
ing the inlet pipe. Connect the vent per code. If installing
outdoors protect the unit from freezing. Install a union
and check valve per valve manufacturer’s instructions.
Install a gate valve on the discharge side of the check
valve for plumbing maintenance. See Typical Installation
Drawing 1.
